The companion to Avoid the Dots (scratch.mit.edu/projects/103604179)! Use the arrow keys to move the white dot. Green dots will award points, and you can keep touching a green dot until it breaks, upon which it will provide many points. If you hit a red dot, it will reduce your health until you move away or it breaks. Rad dots (yellow and white) will continue to follow you, but will eventually deplete automatically. Chad dots (Blue and red) don't directly harm you, but touching them will make lots of red dots spawn. Lean dots (light blue) are power ups! They do different things every time. As the level goes up, certain dots (both good and bad) will gain multipliers and spawn more often.
My ideas only. Enjoy! My highest is 6,448 points on level 55.
